title: Infant pediatric liver transplantation results equal those for older pediatric patients.
abstract: METHODS
  From July 1984 to July 1995, 99 pediatric patients underwent 127 orthotopic liver transplants (OLT) at the University of Wisconsin Children's Hospital. The patients were divided into four groups according to age at time of transplant: group I, 0 to 6 months (n = 20); group II, 6 to 12 months (n = 18); group III, 1 to 2 years (n = 10); and group IV, 2 to 18 years (n = 51). A retrospective analysis was performed to compare these four groups with regard to preoperative indications and demographics, intraoperative technique, complications, and survival. All patients were followed up for 2 to 13 years.
  
  
  RESULTS
  Biliary atresia was the most common indication for OLT in all four groups. The average waiting period varied from 19+/-18 days for group I to 44+/-64 days for group IV. Reduced-size liver transplant (I, 41%; II, 52%; III, 28%; IV, 21%), split-liver transplant (I, 0%; II, 7.4%; III, 17%; IV, 2.9%), or whole-liver transplant techniques were used. Although postoperative Intensive Care Unit stay was longer for the 0- to 6-month-old patients (I, 20+/-64; II, 7.6+/-9; III, 13+/-17; IV, 6.8+/-14 days), the total hospital stay (I, 43+/-63; II, 33+/-34; III, 32+/-20; IV, 29+/-31 days) was similar for all patients. The incidence of hepatic artery thrombosis (I, 19%; II, 19%; III, 27%; IV, 16%), biliary tract complications (I, 4.8%; II, 15%; III, 20%; IV, 14%), and retransplantation (I, 9.5%; II, 41%; III, 33%; IV, 14%) were not significantly different between the four groups. Portal vein thrombosis (I, 9.5%; II, 11%; III, 6.6; IV, 0%) and primary nonfunction (I, 9.5%; II, 7.4%; III, 0%; IV, 3.1%) occurred more frequently in the 0- to 6-month and 6- to 12-month groups, however, the 1-, 5-, and 10-year survival rate for patients (I, 85%, 79%, 79%; II, 89%, 74%, 74%; III, 80%, 80%, 80%; IV, 84%, 75%, 75%, respectively) and primary liver allografts (I, 69%, 69%, 69%; II, 72%, 72%, 63%; III, 70%, 70%, 70%; IV, 71%, 57%, 57%, respectively) were not significantly different (P = .98 and P = .83).
  
  
  CONCLUSIONS
  These results demonstrate that OLT can be effectively performed on infants of all ages and that OLT should not be delayed because of age.
